From the posh suburbs of Short Hills, New Jersey, to the sprawling mansions of Ross, California, INSIDER has rounded up the richest zip code in every state, plus Washington, D.C.

With the help of real estate site Trulia, we used data from the 2012-2016 five-year American Community Survey— a subset of the United States Census Bureau — to calculate the richest zip codes with a population size of over 1,000 in every state, based on median household income. For privacy reasons, the maximum income the American Community Survey will release is $250,001, so any zip code that lists its median income as $250,001 may be higher.

WEST VIRGINIA — 25081

* Although this is the most up-to-date information based on American Community Survey data, there is a large margin of error for some less populous areas like rural West Virginia, where there are fewer people to survey.
